Abstract
The utility model discloses a sleeved current transformer, which comprises an iron core and a secondary winding winded around the iron core. The iron core and the secondary winding form an integrated structure through vacuum casting of an insulating material layer, and a secondary connecting terminal is arranged below the insulating material layer and is connected with the secondary winding through a connecting wire. As the sleeved current transformer is made through the fully sealed casting of outdoor materials, the utility model avoids the defects of oil leakage and oil degradation, realizes the oil-free operation, exempts the annual preventive test of oil-immersed products, and saves a large quantity of manpower and material resources. As the insulating material layer is made of outdoor material, the utility model can be directly used outdoors. The secondary connecting terminal is arranged below the insulating material layer and can be directly arranged on the side of the secondary out-going line of the transformer to enhance the anti-stealing performance.
Description
Technical field
The utility model relates to a kind of current transformer.
Background technology
At present, the monophase current instrument transformer that uses in electric power system all uses indoors, and it can not directly use out of doors, and need add the table case again could use out of doors, thereby can not adapt to the development of existing situation; And the anti-electricity-theft poor performance of traditional monophase current instrument transformer.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can directly use out of doors, the current transformer of thief-proof good electrical property.
In order to solve the problems of the technologies described above, sleeve type current transformer of the present utility model, comprise iron core and be wrapped in secondary winding on the iron core, described iron core, secondary winding form integral structure by the vacuum casting insulating material layer, the below of insulation material layer is provided with the secondary connection terminal, is connected by connecting line between described secondary connection terminal and the secondary winding.
As improvement of the technical scheme, described secondary winding inside is provided with the voltage brass ring, and this voltage brass ring is connected with the secondary connection terminal by connecting line.
The beneficial effects of the utility model are: this sleeve type current transformer is owing to adopt the hermetically sealed cast of exterior material to form,, insulation material layer adopts exterior material, can directly use out of doors; The secondary connection terminal is arranged on the below of insulation material layer, can be directly installed on the secondary outlet side of transformer, has strengthened anti-electricity-theft performance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is an other direction cutaway view of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, sleeve type current transformer of the present utility model, comprise iron core 1 and be wrapped in secondary winding 2 on the iron core 1, described iron core 1, secondary winding 2 form integral structure by vacuum casting insulating material layer 3, the below of insulation material layer 3 is provided with secondary connection terminal 4, is connected by connecting line 5 between described secondary connection terminal 4 and the secondary winding 2.
This sleeve type current transformer has been exempted the shortcoming of leakage of oil and oily deterioration owing to adopt the hermetically sealed cast of exterior material to form, and realizes no oiling, has exempted the preventive trial of annual oil immersion product, has saved lot of manpower and material resources; Insulation material layer adopts exterior material, can directly use out of doors; In addition, secondary connection terminal 4 is arranged on the below of insulation material layer 3, can be directly installed on the secondary outlet side of transformer, has strengthened anti-electricity-theft performance.
Described secondary winding 2 inside are provided with voltage brass ring 6, and this voltage brass ring 6 is connected with secondary connection terminal 4 by connecting line 5, can realize direct power taking pressure.
